PEEISTEEA. 255 



This genus * diflfera from ChamcBpelia in style of coloration, and in having the first 

 primary sharply attenuated at the tip. Both sexes have metallic bands on the wings. 



Three species of Peristera are known, of which two occur within our limits ; the 

 other, P. geoffroyi, is peculiar to South America.

• It seems to us undesirable to change the name Peristera, Swainson, under which genus P. ciiierea has been 

 known for the best part of a century, to Claravis, as has been proposed by Mr. Oberholser, on account of its 

 haviue been used in 1815 in Mollusea, more especially as Peristera, Eafinesque, appears to be a synonym of 

 the prior Columhella, Lamarck.
